all wiwm awesome; 1 no il n l, Joan Bnown, o'i'iiizon of no Unite'vsStates, residing Mls1'isficl.d,-tne county of Rieliloml anal 5 of Ohio,have invented certain l rovemsnts .l loil-lB-m'icls oi wing iss'specification. 7 My invenlion Icolales to that class of cle- Vicesknown as rail bonds the purpose of which is to join the adjacent. endsof rails logc'bsr electrically.

invention has as its object a device zvnich is cosy of manufacture andthereforo 7 I sml which is simple and. cosy fclie mil.

object is to pmdnce a device an n4; often insballolsion in cone aciiriccurrent from mil to roll,

a: soother object is to produce a bond: vliich is capable of beinginstalled by such, means s to mobs iis attachment to the mil powmon-snily ellicient. and avoiding deterioyotion as in the case" of pinexpancled, riveted or bolted type of bonds.

These and other new nnrl useful objects will later ore secured andosi'oinerl by the novel construction, combination and orz'ongement'ofpoints of which my invention comoosofi oncl which will appear later asmore fnll -"ibcd and. claimed and shown in 2w ompaw ings in Wl"lCh3-- iss, elevation of my bond force applied exmic - 335. slim elevation infull of tho boiriii on lane toil and connecting adjacent mil coils oeti'icolly.

have found that a, boncl constructeel of o. copper cable body composedof o olurolity of *wistecl wires or of a. plurality oi ribbonshavingatlnchecl to the ends theisol' by 2 1s a section vnew of the sometermioi o mechonicol algrip, terminsls boil} the body and the terminalto the by Welding or brazing, many (lesirnbls noinls but up to the pres,out time lbey been deficient in one point lbw; i.) bail; on contactarea. between the coppczr body and the metal by which they areoltaclieol to the rail is. not sufficient and time nnicss the terminalsare most securely I 2! cbecl lo lbs ends of the copper cable they linbloto be pulled off; therefore, by my new and novel construction 1 overcomethese objections oncl producc a more eflicient bond from these and otherslandpoints.

In Fig", 1 the flexible body portion is designated by numeral 1 and isusually of copper either wire or ribbon. .Tbe terminal mem- 2 areusually made of steel, iron, nickel or some metallic alloy of these inwhich they predominate, although other metals may be used, and are oftwo parts; namely, a shelf 3 and a. sleeve 4. Through the sleeve is oneor more passages for receiving the body which lerminz-ilo in an enlargedopening 6.

The tsnninal membcr is assembled on the into the recess 6 therebyfilling the recess'[ and the some time extending slightlyobove the face7 of the terminal as designated. by 3. The unsettling of the ends of thebody 1 forms a head upon the body which rests in the recess band therebyprevents the body from ulling away from the terminal after instal ationon the rail; in

brazed union between the two parts would fact tests show that theterminal will come away with the body when the bond is pulled from therail by means of force apphedto the body. The shape of the enlargedpassa e orrecess 6 is not material so long as it is arger than thepassage 5 or of such-shape that an enlarged head can be formed on theend ofthe body 1, resting on the passage 5 and recess 6 and preventingthe body from pulling away fromthe terminal.

The compressing of the sleeve 1 upon the in that it covers all thepoints oi advantage shown in the other figures and described herein, butit does not require the terminal to be recessed or depressed, it beingnecessary only to upset or head over the ends of the body cable 1forming heads 9 upon the upper face of the terminal.

The application of my invention to rails or other conductors to beelectrically connected is performed by meansnvell known in the art andfor which I make no claims. In Figs. land 2 a bond is shown attached toadjacent railends.

laced in position on the rail and then a eating flame of oxyacetylene,electric arc or.other similar means is applied to the rail surface andbond terminal simultaneously and at the same time a rod or stick ofattaching metal is inserted in the flame until the bond terminal andrail are very hot and the attaching metal rod melted and union is madeat that point, then the flame and attaching metal rod are moved to an.adjacent point and the process is repeated until the terminal issecurely attached to the rail, the attaching means. being designated 'bythe numeral 10. This forms an integral union between the bond terminal.the upset body and the rail of highest efliciencv and-one which isporminent.

The use of terminals of iron, steel, nickel or'alloys of such metals andwhich have a higher melting point and test up harder than copper, haspeculiar advantages in that the attaching metal 10 which is usuallyc'opper, bronze or braze, ctc., forms a stronger union with a terminalcomposed of such metals than with one composed of copper as bondterminals are usually made. A terqualities' of the copper body.

The bond isfirst "formed up out of the ends of the bodyand antenna minalso made is cheaper than when made 861 of copper. .When made of iron orsteel as is usual inmy invention the terminal has i very little if anyscrap value' and as it forms a considerable portion of the weight of a.com Jlcte bond, the incentive to steal, the hon s, as is quite general,is practically overcome. f

Upsetting the ends of the copper body 1 and forming an enlarged mass hasbeen found to possess the advantage of protecting the smaller mass ofcopper below the upset head from the high temperature of the heatingflame in that the mass in theupset co er head tends toreceive and absorbt e lieat, thereby preserving the original good It will be observed fromFig. 4. that a area of the recess or enlarged passagecfi is greater thanthat of the passages 5 and this is of mutual advantage in that the unionbetween the'copper body 1 which entirely fills the enlarged passage 6and the attach- 7 ing metal used in installing will be greater than ifthe ends of the body 1 were not compressed andexpanded. This insures anare of contact between the attaching metal and the bond body greaterthan the cross sect area of the metal opposing thebody and which is verydesirable.

The end 8 of the upset body being allowdd to extend slightly above'theface of the terminal has been found of advantage in that it permits theattaching metal to take a better hold on the copper body than if it werebelow the face of the terminal or just flush. v

Having shown and described my invention, I do not wish to be limited tothe exact construction shown and described, as there are variationswhich can be made and which will be readily recognized by one skilled inthe art and which will come within the scope of my invention, but what Ido claim and desire to secure by Letters Patent is 1.
